Check if try_parse() errors due to --help

[fabolous005]

i want to parse my struct with try_parse(), but continue if it fails.
Unfortunately it fails when --help is passed (which should definitely not be the case). so easiest way would be to check if the thrown error was due to --help.
Is there a way to do this, is there even an unique error type for that?

You want Error::use_stderr which is what we use in other cases like determining the exit_code.

(which should definitely not be the case).

Error not not necessarily mean "something bad happened" but "this can't continue as normal" which is what we do for --help. This is a big help in the implementation and for users so they can "exit early" for this non-recoverable parse state.

I'm sure of it i just mean for my usecase... sorry for being unclear

You want Error::use_stderr

And while this prints out the error it cant fulfill my needs, as my application should exit if the "error" was due to --help being passed

I'm not too sure what you are saying. From your description, you want to know if the error is because of --help. use_stderr is an oddly named function to tell you whether the Error is because the parse failed or because of --help / --version. You could also check the ErrorKind directly.

oh you're right i thought i knew this on, but i confused it with something else.
Thank You!
